Ansible in 100 Seconds

Ansible is a popular configuration management tool created by Michael Dahan in 2012 and later acquired by Red Hat. It uses declarative YAML code to automate Linux server management, reducing human error. Ansible operates with a control node that connects to managed nodes via SSH, executing tasks defined in playbooks. Playbooks are item potent, ensuring changes are only made when necessary. A practical application is managing Linux servers on Lenode, where Ansible can be installed on a control node to automate server provisioning. Ansible Galaxy offers a vast ecosystem of prebuilt playbooks, and Vault can be used to securely store sensitive information. Creating a playbook involves defining tasks and configurations, which can be executed to automate infrastructure management.

Who created Ansible and in what year?

• Guido van Rossum in 2008

• Linus Torvalds in 2010

• Red Hat in 2015

• Michael Dahan in 2012

What is the primary benefit of using declarative YAML code in Ansible?

• It automates Linux servers, reducing human error.

• It increases the complexity of server management.

• It requires more human intervention.

• It allows for manual server configuration.

What is a key feature of Ansible playbooks?

• They are executed randomly on target hosts.

• They can only be used once.

• They are idempotent, making changes only when necessary.

• They require constant manual updates.

What is the purpose of using Ansible Galaxy?

• To manually configure servers.

• To access a massive ecosystem of prebuilt playbooks.

• To disable automation features.

• To write playbooks from scratch.

What is the final step in automating server creation with Ansible?

• Writing a new playbook from scratch.

• Running the Ansible playbook command.

• Manually configuring each server.

• Disabling the Ansible module.
